LAD: calcific vessel,moderate stenosis in mid course. minor osteal disease at the orgin of D1 & D2. LCx;Non-dominant. minor irregularity proximally , critical disease in  mid segment. 1st OM has moderate disease in its proximal segment. RCA;Dominant. spotty calcification. diffuse minor disease proximal to mid segment. PDA has moderete/ subcritical osteal disease.
My BP is normal . Non diabetic. Coronary angiogram with view to PCI to Cx has been advised by a cardiologist. Should I go for it?
